IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 21,827, dated October 19, 1858.

To all whom it may concern:

Be it known that I, RosEwELL H. FIs11ER, of Olaremont, in the county of Sullivan and State of New Hampshire, have invented certain new and useful Improvements in Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the employment and arrangement of the several parts of the machine, which will be hereinafter particularly described.

In the annexed drawings, Figure 1 is a perspective view of the machine. Fig. 2 is a perspective view of the cutters, fingers, and plate which covers them. Fig. 3 is a perspective view of the camshoe and its means of attachment.

In Fig. 1, A represents the driving-wheel of the machine, the peculiarity of which consists in its being provided on its inner rim with small friction-rollers, which are placed in two rows sufficiently wide apart to allow a camshoe, b, to pass between them. These rollers 11 a are secured to the wheel bya small pin or axis, which passes through them, and on which they turn.

B B represent that portion of the frame of the machine in which the driving-wheel has its bearings.

0 represents the position of the platform on which the grain falls after being cut.

I) is a wheel which supports one end of the platform and cutting apparatus, &c.

1) represents a cam-shoe, the form of which will be seen in Fig.3, which traverses the space between the two sets of rollers. The rollers are so placed that if any three of them are taken, two on one side and one on the other, and lines drawn between them an equilateral triangle will be formed. Thus being placed in a regular manner but not opposite each other, it will be seen that when the bulging cam sides of the shoe come in contact with the rollers only one side comes in contact at a time, and this striking against the roller, the shoe is partially turned, but, passing on the other side, strikes a roller on the opposite side and turns it back, thus giving it a zigzag motion around the wheel.

e represents a rod, which is connected by a pivot to the tail end of the shoe. This rod passes through a guide, u, which is secured to the slide-bar c. This bar cis provided with a small pin, m, which works in a groove in the eccentric-wheel d. To this wheel dis connected a rod, near its periphery, on its side, and to said rod is secured a lever, g. By working this lever g backward and forward the wheel d is turned partially around and back, thus elevating and lowering the bar 0 and rod e. The object of raising and lowering the rod eis this. Said rod beingprovided with a small hole, into which fits a pin, 2:, on the cutter-bar, motionmay be given or taken from the cutterbar at any moment. When the rod 6 is raised the pin 2 comes out of the hole, thus disconnectin g the rod from the cutter-bar. The rod 0, being secured in the guide u, is precise in its movement, and although the machine may be moving rapidly and said rod disconnected, by a simple movement of the lever y it will con nect with the cutter-bar and set it in motion. At the rear end of the fingers and between them are situated the small wheels '11. n it. These wheels are embedded in the finger-plate, and are slotted on top, so as to admit the cutters. The cutters i i are pivoted to the cutterbar K at their rear end, and pass through the wheels 11 n 'n and fit in the slot in them very snugly. When the cutters are in motion the wheels turn partially and the cutters are allowed to draw through the slot in them when necessary.

his a cap which fits over the cutters and wheels, as will be seen in Fig. 2. This cap is so constructed, having the little lugs l l 1 between the wheels, that when -fit on the wheels may turn readily without allowing any dust or dirt to enter and prevent the operation of the cutters.

p and p are two pulleys connected together by the band N. p is secured to the shaft of the driving-wheel; but 10 is on a separate shaft and is intended to drive the reel.

.9 is a small pinion on the same shaft with pulley p, and gears into a pinion, s, which is secured to wheel J. Wheel J is on the same shaft with pulley p and pinion s, but turns to the grain and the cutters.

E is the tongue of the machine,and m audl are levers, which, being connected to said tongue and also to the frame, serve to raise and lower the cutting apparatus when desired.

In operating this machine the driver sits upon the seat F. He there has command of the lever I, which raises or lowers'the cutting apparatus, and also the lever g, which throws the cutter-bar in and out of gear. ing set to suit the grain, the driver may easily adapt the machine the desired cutting height, and when itisnotnecessary to cut at all he may throw the cutter-bar out of gear, and thus move the machine to any desired point. The facility with which this machine may be operated, its simplicity of construction, and the mode of preventing the cutters from being damaged The reel H beby dust and dirt are all great advantages in its favor.

Having thus fully described my invention, What I claim asnew, and desire to secure by Letters Patent, is

l. The combination of the connecting-rod e, slide-bar c, eccentric-wheel d, rod f, and lever g with the cutter-bar K, for the purpose of throwing said cutter-bar in and out of gear when the several parts are arranged and operated as herein set forth.

2. The arrangement of the plate h, the cut-' 3. Securing the reel H to the wheels J J,

when it is operated and adjusted by the means herein set forth, and for the purpose specified.
